Studies Potato Starch Wastewater Ultrafiltration and Mass Transfer Process

doi:10.7506/spkx1002-6630-201511010

Abstract

Abstract:

Ultrafiltration was used for concentrating potato starch wastewater. This study investigated the relationship
explore the between changes in membrane flux and protein concentration at room temperature and 0.16 MPa. The mass
transfer equation describing the ultrafiltration process was developed which indicated that the concentration (ρg) of potato
protein for forming a gel layer was 71.582 g/L. A model of membrane flux as a function of operating pressure based on the
resistance model theory was establishedwhich will be benefit for exploring the influence of different operating pressure on
membrane fluxunder.

Key words: ultrafiltration, potato starch wastewater, membrane flux, mass transfer equation
